After trading my eotech and 3x magnifier for what my heart was set on orginally, so I decided on a TA31F with kill flash installed, which makes it as close to a TA31RCO-M150CP without the ranging lines to the right and left of the retical. This was shot at about 240-250 yards with my LMT, the optic was a TA31F with flashkill installed, I was pretty impresed with it acog initially when my unit got them , which drove me to finally get one my self, well, what adjustments would you make if any, with a grouping like this at 250, it is the first time out with my own personal acog and the ammo I was using was federal xm193 , and I know or hope I can tighten it up next range outing, well tell me what you think?
